To many of their sounders and electronic chart display devices, LOWRANCE have added a new feature which permits the user to capture the screen display to a file which is stored on a removable Multi-Media Card-Secure Data (MMC/SD) memory card. The MMC/SD memory card can then be removed from the Lowrance device and mounted in the file system of a computer with an appropriate memory card reader hardware device. This new feature allows users to make recordings of SONAR echograms.The SONAR echogram files are stored using a JPEG image compression algorithm.
The screen capture feature is provided in the latest software update from Lowrance.

Previously Lowrance SONAR devices were able to make sophisticated recordings of long series of echograms, but unfortunately this feature required use of a binary executable which was only available for users of the Windows operating system. The new screen capture feature works with any operating system that can display a JPEG image and can mount the file system on the MMC/SD card.
The ability to make a screen capture of a SONAR echogram will be of interest to many users of Lowrance sounders. Lowrance joins other manufacturers of recreational boat echo sounders who also offer this feature.
More Support for Non-Windows Operating Systems
In addition, Lowrance appears to be recognizing the existence of non-Windows operating systems computers. They have provided the update software package as a JAVA program that performs the download and transfer of the update package. The JAVA applet is provided as part of a web page link on the Lowrance web site. I tested this feature with my MacOS 10.4 system. It appeared to work perfectly, and the update package was transferred to my computer. If during the JAVA execution you have a MMC/SD read-write memory card mounted in a memory card writer, the JAVA program will store the file onto the MMC/SD memory card.
To upgrade the Lowrance device, you install the MMC/SD memory card in the slot on the sounder or electronic chart display device. When the device is turned on the upgrade is automatically executed.
By using a JAVA approach, Lowrance has made the upgrade process available to users of LINUX or the MacOS, in addition to its usual Windows software users.
I have a Lowrance LMS-520C on my bench for some testing, and I hope to be able to install the upgrade and obtain some screen captures.
